TESO scrapped its subscription free earlier this year, which means you can play all of its content without having to pay a dime beyond the initial purchase price.
Developer ZeniMax Online has generally done a good job of transforming it into one of the best MMORPGs currently available on consoles. But at the same time, The Elder Scrolls Online feels at home on the Xbox One and PS4, as though it were made for them from the start. Granted, the launch week has been hounded by server instability and lag (that seems to be clearing up in the wake of a couple of patches), and I'm still not a big fan of the console versions' voice-only approach to socializing.
